IMPEOVEMEET IN GENTRIFUGAL MACHINES FOR DRAINING SUGAR AND OTHER SUBSTANCES.

'd'ln firlgeinh reform! in intlgrss riters some not mating part c Ilge smut.

TO ALL WHOM IT llIAY oononnni Be it known that 1, DAVID M. Wnsrompr" Boston, count invented a new and useful Improvementin Centrifugal Machine declare that the following is a full, clear y of Suil'olk, and State of Massachusetts, have s for Sugar and other Material; and I do hereby and exact description of the constructioh and operation of the some,

he and use the same, reference being had to the annexed drawings, making part of this specification, in which' Figure 1 is an elevation of my invention.

Figure 2 is a. vertical section of the same.

Figure .3 shows the pulley with the shaft and cylinder detached therefrom. Figure 4 is a plan of the top of the cylinder within the tub Figure 6 is a horizontal section of' the cylinder and tub on the line A B so as to exhibit partially the outlets in the bottom,

' a is a frame from which the invention is suspended. the rubber bushing or spring, a. c is a. rubber bushing or spring within the box I), in which the spindle dis hung. d is an upright spindle hung by a flange on its upper end in the rubber ihushing c, and in which the rotary parts of the machine are hung and revolve. e is an upright hollow shaft encircling the spindle d, with 1'. driving-pulley firmly attached to its upper end, and a revolving cylinder,g, attached below, travelling on antifriction collars, and supported by escrow-nut attached to the lower end of the spindle d. fis a driving-pulley attached to the upper end of the hollow shaft e. g isa. revolving cylinder, with an opening in the top and perforated sides, attached to the hollow shaft e at its lower end, made to contain sugar or other material to be acted upon by centrifugal force. it is a tub in which t which are separated by centrifugal fdrce from the sugar or other materi the bottom of the cylinder g, to permit the discharge of the solid materialafter it is acted upon. is a movable valve adjusted by a hollow neck or stem, so as to slide up and down'upon the shaft e.

The nature of my invention consists, first, in substituting for the fixed bearings commonly used, nflexible hearing, so that the revolving cylinder, which may be made in any of the common forms, may be suspended from the top by flexible connections, so as to admit a free lateral movement while it revolves, thus overcoming by the-uneven distribution of the weight of the materials to be acted upon,- y saving a great expenditure of power, much and great weight and expense of machines, and foundations to secure stability;

al acted upon. 1' 2' 2' t are openings in elevating or otherwise opening a. valve in its bottom. I constructs, cylinder to contain the material to bo'acted upon in any of the common forms, with the usual opening in th e top, andwith perforated sides, which I attach to the lower end of the upright hollow shafts, to which, at the upper end, is uflixed the pulley f, the whole revolving on the spindle d, which is suspended in the flexible bushing 0, within the box 6, allowing the hollow ith a free lateral-movement; In the bottom of the cylinder 5! I construct the openings ii i 1'; which may vary in form, and which are closed by the inovable valvej, which is attached. loosely to the upright shaft e, as shown in fig. 2. This cylinder being filledthrough the opening in the top, with the valvej resting upon and covering the openings a z'iz'in the botto n, power is applied to the pulley faflixed to the upright shaft e, and the cylinder g, with its contents, revolves rapidly and freely upon the spindle suspended in the rubber bushing c, which find its own hentre, upon the axis of which-it revolves without jiir or concussion. After the sugar or other material containodin the revolving cylinder has been acted upon, and the liquids separated and discharged through the apertures in the sides by the centrifugal force thus created, the valve j is 1' aised, and sliding upwards upon the shaft e, the contents of the cylinder are e above described. Other forms of bearings pose, such as what is commonly called the he cylinderg revolves, forming a receptacle for the liquids enables the revolving moss however unevenly its weight may be distributed, to

universal joint, or 'by connecting the upright shaft with its support by means of a ball-joint or thin disk plate or other flexible connections.

' lclaim-the construction of centrifugal machines made to separate liquids from other substances, by suspending such machines at the top by flexible ccnnections operating substantially-as above described.

I claim the construction of the openings 1' i i i in the bottom. of the cylinder g, in such machines, and the valv j, for the purpose and operating substantially as above described.
